This course introduces major topics in Web3, breaks down the Ethereum stack and gives an overview of the current UX in Web3 and what pain points still exist.

This course introduces the project that we will be working on for the duration of the course and demonstrates how to set up a wallet for your project, Web3 libraries like viem and wrappers like wagmi.sh and how to set up a React frontend to read and write from the blockchain.

This module delves into the essential principles of building secure decentralized finance (DeFi) applications, with a focus on front-end development best practices. You’ll learn how to safely handle ERC-20 tokens and other assets, ensuring secure interactions between users and DeFi protocols, while setting the foundation for integrating more complex DeFi functionalities like token swapping.

Building on secure token handling, this module guides you through the practical steps of integrating token swapping functionality into DeFi applications. You’ll learn how to interact with leading DeFi protocols, like 0x, and implement seamless token exchange features directly into your decentralized applications (dApps), ensuring smooth and efficient user experiences.

In this module, you’ll explore the concepts and tools behind onchain authentication, empowering developers to create dApps that can securely verify user identities and actions directly on the blockchain. You’ll learn how to implement decentralized authentication systems, ensuring your Web3 applications are not only functional but also highly secure and privacy-conscious.
